“…Several cohort studies also suggested an increased risk of liver cancer in subjects exposed to asbestos. 110,111 for iCCA risk was reported among subjects occupationally exposed to asbestos for over 30 years; a limited evidence was instead reported for eCCA (OR = 2.09, 95% CI 0.83-5.27). 112 ).…”

Cholangiocarcinoma (CCA) is a heterogeneous disease arising from a complex interaction between host‐specific genetic background and multiple risk factors. Globally, CCA incidence rates exhibit geographical variation, with much higher incidence in parts of the Eastern world compared to the West. These differences are likely to reflect differences in geographical risk factors as well as genetic determinants. Of note, over the past few decades, the incidence rates of CCA appear to change and subtypes of CCA appear to show distinct epidemiological trends. These trends need to be interpreted with caution given the issues of diagnosis, recording and coding of subtypes of CCA. Epidemiological evidences suggest that in general population some risk factors are less frequent but associated with a higher CCA risk, while others are more common but associated with a lower risk. Moreover, while some risk factors are shared by intrahepatic and both extrahepatic forms, others seem more specific for one of the two forms. Currently some pathological conditions have been clearly associated with CCA development, and other conditions are emerging; however, while their impact in increasing CCA risk as single etiological factors has been provided in many studies, less is known when two or more risk factors co‐occur in the same patient. Moreover, despite the advancements in the knowledge of CCA aetiology, in Western countries about 50% of cases are still diagnosed without any identifiable risk factor. It is therefore conceivable that other still undefined etiologic factors are responsible for the recent increase of CCA (especially iCCA) incidence worldwide.

“…The workers of the ship breaking industries have to work in a hostile environment with toxic substances like asbestos, thus they suffered from overall cancer, esophagus cancer, trachea bronchus and lung cancer etc (Wu et al, 2015 andMuhibbulahh et al, 2014). In case of the injuries and diseases suffered by the workers in the Sitakunda ship breaking yards, the loss of body parts is the most serious one.…”

The coastal area of Bangladesh is one of the most ecologically productive and it contains a rich biodiversity which includes several species that are endemic to this region. Much attention has been focused on ship breaking industries in the coastal areas because of the threat they pose to this thriving biological communities along with their other environmental impacts and the perilous working environment of the workers. The coastal environment of Sitakunda is severely contaminated by various processes related to shipbreaking i.e. the disposal of different toxic wastes into the sea water, deforestation by expanding ship breaking yard, changing land-use pattern and release of toxic substance into the soil. Moreover, the workers of this industry are exposed to an extremely risky and toxic working environment which makes them vulnerable to both physical and psychological disorder as well as to accidental deaths and injury. Still, workers embrace these risks for very poor wages and most of the profits go to the already rich businessmen. Despite various negativities, this industry has gained importance due to the increasing demand of raw material for re-rolling industries and employment opportunities for the people of the coastal areas.

Oral and pharyngeal cancer risk associated with occupational carcinogenic substances: Systematic review

et al. 2018

View full text Add to dashboard Cite

Background Oral and pharyngeal cancers (OPC) represent the seventh most common type of cancer and the seventh leading cause of deaths by cancer worldwide. Few studies have assessed the occupational exposure risks associated with OPC and in many cases the results are conflicting. The aim of this study was to determine, through a systematic review, the association of OPC and exposure to different occupational carcinogenic substances. Methods The addressed focused question was “Is there an association of occupational carcinogenic substances with OPC?” PubMed, MEDLINE, EMBASE, and ISI Web of Science databases were searched between January 1995 up to and including July 2016 using the keywords “oral cancer,” “pharyngeal cancer,” “pharyngeal neoplasms,” “oral neoplasms,” “occupational disease,” “occupational exposure,” and “occupational risk factor” in various combinations. Letters to the Editor, review articles, case reports, and unpublished articles were excluded. Results Fourteen original articles were included. Majority of the studies were conducted in European countries and used a case‐control design. The results showed a significant association between formaldehyde, wood dust, coal dust, asbestos, welding fumes, and risk of developing OPC, while marginal association was observed with metal and leather dust. No associated risk was observed for textile fibers. Conclusion There is some evidence to suggest associations of occupational substances with OPC, particularly in the pharynx. Future well‐designed studies are required to confirm or rule out with confidence the associated exposure risk of these substances.
